I had to chuckle when I saw the domain this story was submitted from. On one hand, the technical aspects of Quora are quite nifty. But the interaction process is one big 'wtf'. Adding new topics to your feed is baffling. In fact for a while I didn't even realize there was a personalizd feed, I thought the majority of questions were just about Steve Jobs (must have been cause ceoSteveJobs is on my Twitter account, which I used to sign in). Other details, like wanting to post a question in anonymous mode, have inobvious answers. It's a shambles (although I suppose it's still early days, and really the content is the important thing).
